Abstract


This paper studies the circulating cooling water , dissolved oxygen , pH value , alkalinity, and other environmental corrosion factor circulating cooling water system corrosion . Made of carbon steel and 304 stainless steel as an experimental sample , in the preparation of a uniform design solution available to potential continuous scanning corrosion testing of carbon steel specimens and 304 specimens , respectively . The results showed that the corrosion rate of carbon steel specimen and 304 steel specimens with Cl - , total dissolved solids, alkalinity concentration increases gradually increased rapidly at first increases and then decreases with the concentration of dissolved oxygen . Finally , use of the experimental carbon steel corrosion data correction Pisigan and Singley the forecast carbon steel corrosion rate mathematical model , stainless steel corrosion data used in the simulation circulating cooling water drawn carbon steel corrosion rate of stainless steel corrosion rate with Pisigan and Singley the relationship between the model .
